Amazon Elastic Container Registry

Working with Docker makes one realize how valuable container images are in enabling the packaging of an application and its dependencies into a portable unit. Whether we’re building a microservice architecture or deploying serverless functions that require container runtimes, Docker images are central to modern application delivery.

Organizations deploying multiple containers require a registry to store, maintain, and distribute different images. A container registry is crucial in the Docker ecosystem to provide a reliable and scalable infrastructure for sharing and collaborating on container images across different environments.

We can use the Amazon Elastic Container Registry (ECR) for container management. It enables reliable and efficient container deployment, facilitates version control, and ensures consistency in application delivery.

Amazon Elastic Container Registry

Amazon Elastic Container Registry (ECR) is an AWS-managed Docker container registry service. It provides a secure and scalable repository for storing and managing Docker images. It offers both public and private registries and allows us to store multiple repositories in these registries.

Amazon ECR supports two types of registries: private and public, each suited for different collaboration and distribution models:

• ECR is primarily designed as a private registry, meaning that it’s intended for use within organizations or teams. We can push our Docker images to ECR and control access permissions to ensure that only authorized users can pull or modify these images. These private registry repositories are available only to authorized IAM entities.

• ECR also offers public registries, which are container registries publicly accessible to anyone on the internet. It hosts a wide range of open-source and community-contributed Docker images, making them readily available for ...
